What I nice book. It has been quite some time since I have read a science fiction book and I don't remember why I quit reading them. The fact that this book talked about social media made the book that much better.
I sure hope that the future does not depend of 'whuffie' or anything like it. I lead a predominately solitary existence with the exception of my immediate family and a few coworkers. I'm sure I would be hurtin' for whuffie.
I also licked the concept of living forever and making periodic backups and using restores to get past fatal mistakes in your life. Thinking through this concept would cause most people to change the way they live their lives.
Bottom line, I would very much recommend reading this book. It is quite short at only 69 pages and should not take too much time to read. Certainly time well spent.
